Antenna dish reflector with integral declination adjustment

Abstract

An antenna system for a television reception only antenna includes an integral declination adjustment comprising an upper and lower curvilinear surface as part of the superstructure supporting the main reflector dish with an upper and lower pad rotatably mounted to a pivot tube providing surfaces matching the curvilinear surfaces against which the main reflector dish rests. Slots and holes are cut into the matching surfaces and a pair of nut and bolt assemblies extending through the slots and holes secure the surfaces once the proper declination angle has been achieved.

What is claimed is: 
     
       1. An antenna for receiving satellite broadcast data, the antenna comprising a main reflector dish, means to rotatably mount said main reflector dish from a support, said support comprising a rod means defining an axis of rotation of said dish to adjust the azimuth thereof, said rotatable mounting means including integral means to adjust the declination of the dish with respect to the support, the declination adjust means comprising an upper and lower pad means rotatably secured to the rod means, an upper and lower surface secured to the dish, and means to mount said upper and lower surfaces to said upper and lower pads. 
     
     
       2. The device of claim 1 wherein one of each of the pads and surfaces have means defining a slot therein, and means defining a hole in the other of each of the pads and surfaces, the surface mounting means comprising means for insertion through said slots and holes. 
     
     
       3. The device of claim 2 wherein the surface mounting means comprises a plurality of nut and bolt assemblies. 
     
     
       4. The device of claim 3 wherein the rod means comprises a pivot rod and wherein each of the upper and lower pads have a curvilinear surface, said upper and lower surfaces being curvilinear to match said pad curvilinear surfaces so that said upper and lower surfaces slideably support the dish from the upper and lower pads. 
     
     
       5. The device of claim 4 wherein the slots are in the upper and lower surfaces and the holes are in the upper and lower pads. 
     
     
       6. The device of claim 5 wherein the antenna is for a television reception only (TVRO) application. 
     
     
       7. An antenna for use in a satellite television reception only (TVRO) system, said antenna comprising a main reflector dish, the main reflector dish having an upper and lower curvilinear surface at its rear, an upper and lower pad, a rod means, said upper and lower pads rotatably mounted to said rod means, each of said pads having a curvilinear surface to match the upper and lower curvilinear surfaces on said dish, and means to secure said upper and lower surfaces to said upper and lower pads, said securing means having means permitting sliding movement between said surfaces and pads to thereby adjust the declination of the dish with respect to the rod means. 
     
     
       8. The device of claim 7 wherein one of each of the pads and surfaces has means defining a slot therein, and means defining a hole in the other of each of the pads and surfaces, said securing means including means for insertion through said slots and holes to secure said pads and surfaces. 
     
     
       9. The device of claim 8 wherein the insertion means comprises a plurality of nut and bolt assemblies. 
     
     
       10. The device of claim 9 wherein the slots are in the upper and lower surfaces and the holes are in the upper and lower pads. 
     
     
       11. In an antenna for receiving satellite broadcast data, the antenna comprising a main reflector dish, said main reflector dish having a supporting superstructure, and means to rotatably mount said supporting superstructure from a support, the improvement comprising means integral with said supporting superstructure to adjust the declination of the dish with respect to the support, said integral declination adjustmnet means comprising upper and lower pads rotatably secured to said support, each of said pads having a curvilinear surface, said supporting superstructure having matching upper and lower curvilinear surfaces, and adjustment means to permit slideable adjustment of said pad curvilinear surfaces and said supporting superstructure curvilinear surfaces to thereby adjust the declination of the dish with respect to the support. 
     
     
       12. The device of claim 11 wherein the adjustment means includes a slot in one of each of the pads and supporting superstructure curvilinear surfaces, and means defining a hole in the other of each of the pads and supporting superstructure curvilinear surfaces, and means for insertion through said slots and holes. 
     
     
       13. The device of claim 12 wherein the insertion means comprises a plurality of nut and bolt assemblies. 
     
     
       14. The device of claim 13 wherein the support comprises a pivot rod, said upper and lower pads including cylindrical openings therethrough so that said pads may be slid onto said pivot rod.
